Answer:
The diameter of the tire is 1.274 m
Explanation:
Given;
total length of the street, L = 172 m
let the radius of the tire = r
let the diameter of the tire, d = 2r
In every single turn, a tire covers a distance, D = 2πr
for the total 43 times, the distance covered, D = L = 43 x 2πr
L = 43 x 2πr
172 = 86πr
d = 2r = 2 x 0.637
d = 1.274 m
Therefore, the diameter of the tire is 1.274 m
